The HEPA filter integrity test is typically performed on supply air or exhaust air HEPA filters using a photometer to scan the filter surface for pinhole leaks that could allow the transmission of contaminant particles that would be unacceptable in a critical application. To perform testing, adequate access needs to be available to physically view and scan the HEPA face.

The most-common onsite HEPA integrity test method is the Cold DOP test, as described in AS1807.4.4 and 1807.7.

At the conclusion of our comprehensive testing, you will receive a detailed analysis report and a NATA accredited certificate of compliance to verify HEPA filter integrity as per Australian Standard specifications.
